Magnetic inductive flowmeter installation points: selection of full pipe, straight pipe section principle, anti-interference, suitable materials, sealed installation. Ensure that the specification is accurate, to provide reliable data support for industrial production.

Project Overview

To ensure that the magnetic inductive flowmeter installation specifications are correct, you need to follow the following key steps and precautions:

1. Choose the appropriate installation location:

  • Installed at the lowest point of the pipeline or vertical pipe section to ensure that the fluid is always filled with the pipe (full pipe state).

  • Avoid installation at the top, ends, or turns of pipes, as these locations may not keep the pipe full.

  • For vertical installations, ensure fluid flows from bottom to top.

2. Comply with the requirements for straight pipe sections:

  • The front straight pipe section should be at least 5 times the pipe diameter, and the rear straight pipe section should be at least 3 times the pipe diameter (the principle of five in the front and three in the back). Special circumstances may require a longer straight pipe section.
  • If there are interfering factors around (such as elbows, valves, diameter reduction, etc.), the straight pipe section may need to be extended.

3. Avoid interference:

  • Stay away from strong electromagnetic field sources, such as large motors, transformers, frequency converters, etc., to prevent measurement signals from being interfered with.

  • Avoid installation in an environment that is humid, prone to water accumulation, or in extreme climate conditions (such as strong sunlight or rain) to avoid affecting the stability of the equipment.

4. Consider pipe materials and linings:

  • Make sure the pipe material is compatible with the flow meter to avoid chemical corrosion or electrochemical reactions.

  • Select the appropriate lining material based on fluid properties to protect the sensor and reduce measurement errors.

5. Correct installation:

  • Check that all interfaces and flange connections are well sealed to avoid leaks.

  • The installation should be convenient for later maintenance and repair, and a location that is easily accessible should be selected.

Through the above steps, the safety of the magnetic inductive flowmeter can be effectively ensured.The installation is both standardized and accurate, thereby providing reliable data support in industrial production.
